Taper roller bearing, has taper rollers arranged between outer ring with outer raceway and inner ring with inner raceway, where inner raceway and circular guidance surface are connected by transition section, which is defined by radius

摘要

The bearing (1) has a set of taper rollers (5) arranged between an outer ring (6) with a conical outer raceway (7) and an inner ring (8) with a conical inner raceway (9). The inner ring comprises a large board (20) with a circular guidance surface and a small board (21). The inner raceway of the inner ring and the circular guidance surface are connected by a transition section, which is defined by radius. The transition section is formed by a segment of circle from the inner raceway of the inner ring to the circular guidance surface, where usable length of the inner raceway is increased.
